Laser marking application on prototypes
Laser marking application on prototypes
Laser engraving or laser marking, is based on numerical control technology, laser as the processing media. The physical denaturation of instantaneous melting and gasification of processed materials under laser engraving irradiation can make laser engraving achieve the purpose of processing. Laser engraved words have no marks, the surface of the object is still smooth, the writing will not wear.
The characteristics of laser processing: no contact with the material surface, not affected by mechanical movement, the surface will not be deformed, generally without fixing. Not affected by the elasticity and flexibility of the material, convenient for soft materials. High machining accuracy, high speed, wide range of applications.
Using a laser to engraving and cutting, the process is as simple as printing on paper using a computer and printer; Scanned graphics, vectorized graphics and various CAD files can be easily "printed" into the engraving machine. For example, if you want to make a variety of color of the product, it’s words have red, yellow, blue, and gray color, the key body is white, laser engraving, the painting is red, yellow, blue, grey corresponding, be careful not to spray onto other areas,.
At the same time, if you want to some areas be transparent, use PC or PMMA, spray a layer of oil, carved out the font part, then there is light below it out, but at this time to consider the adhesion performance of various oil, cannot be easily rubbed off. The font of different colors do not get too close, otherwise it is not good to spray oil.
Laser carving is generally used in the processing of transparent prototyping parts. How to make one? First of all, we choose transparent materials and spray paint to remove the carving. Generally, such as LOGO, product name, number, number code and other locations that need to be transparent to light. When it is not luminous, it is the same color as the whole product. If the luminous part is on, the part removed by the carving will be transparent to light. The laser carving is also commonly used in aluminum products, aluminum laser carving out the effect is generally better than screen printing, and will not fade.
